Enhancement methods in image processing

Image enhancement is the process of adjusting digital images so that the results are more suitable for display or further image analysis. For example, you can remove noise, sharpen, or brighten an image, making it easier to identify key features.

Here are some useful examples and methods of image enhancement:

The following images illustrate a few of these examples:

Correcting nonuniform illumination with morphological operators

Image enhancement algorithms include deblurring, filtering, and contrast methods. For more information, see Image Processing Toolbox™.
